STELLAR SR Series 3-Phase Motor Soft Starters
General purpose soft start motor control applications where traditional across-the-line starting or wye-delta starting would typically be appropriate. Typical application types include:
The SR22 series motor soft starters use thyristors for controlled reduced voltage motor starting and stopping. These low voltage soft starters then switch to internal contacts for efficient running at the rated speed.
SR33 semi-conductor solid state soft starters provide many advantages when used instead of electro-mechanical contactors to control 3-phase AC induction motors, and are designed to fit in place of existing wye-delta starters.
SR55 soft starters are fully digital, and use thyristors in all three motor phases for controlled reduced voltage motor starting and stopping. SR55 series starters have an Automatic Application Setup that fully configures the starter for a specific application with one entry. And the SR55 series has built-in internal bypass relays and patented iERS (intelligent Energy Recovery System) that reduces energy costs when used on lightly loaded and oversized motors.
